Figure 2
The distribution of the phenotypic effects of alleles present in population one that cause adaptive differences between it and population two. The solid line corresponds to the directional selection case where divergence occurred for 103 generations and the fitness parameters were o1=1.0, o2=−1.0, σ1=1.0 and σ2=1.0. The dotted line corresponds to the directional selection case where divergence occurred for 104 generations and the fitness parameters were o1=10.0, o2=−10.0, σ1=1.0 and σ2=1.0. The dashed line corresponds to the case when the divergence time was 104 generations and stabilizing selection occurred. The fitness parameters in this case were o1=0.1, o2=−0.1, σ1=1.0 and σ2=1.0. The average magnitude of the selection coefficient of a mutation was 0.01.
